POWER MECHANISM.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed May 3,1906. Serial No. 315,080.

To (LZZ/ whom it may concern:

Be it'known that I, EMERY C. Hoocns, a citizen of the United States,residing at Bloomington, in the county of McLean and State of Illinois,have invented certain new and useful Improvements in Power Mechanism, ofwhich the following is a specification.

My invention relates to improvements in power mechanism, and has for itsobj ect, the provision of a device of this character which may be usedfor driving the line shafting in factories and similar places, and whichwill be simple and durable in construction and will perform itsfunctions in a practical and efiicient manner.

With these and other objects in view my invention consists of a powermechanism embodying certain novel features of construction, combinationand arrangement of parts substantially as herein disclosed.

Figure 1, is a top plan view of my improved machine. Fig. 2, is a sideelevation thereof, and Fig. 3, is a detail view partly in section toillustrate the dog and connection with the sprocket chain.

Referring to the drawings in detail: The numeral 1, designates a pair ofbearing stand ards in which is mounted a shaft 2, provided with the flywheel 3, and having secured on its end, the crank disk or wheel 4. Thisshaft is the driven shaft and may be connected with any suitable sourceof power. A crank pin 5, is carried by the crank disk, and is providedwith the securing nut 6, and en gaging said crank pin, is the slottedyoke 7, of the lever arm 8. This lever arm is pivotally mounted in thepedestal 9, and at its oppositeend, is formed with the slotted extension10, which is on a plane at right angles to the slot in the opposite endof the le ver. This connection with the driven crank disk gives thelever a long-arm leverage movement. Pivotally mounted in a similarpedestal 11, is a lever 12, the slotted longarm 13, of which, engagesthe slotted shortarm 10, of the lever arm 8. The forward end of thelever 12, is broadened and formed with a longitudinal opening or slot14, through which the sprocket chain 15, passes. This sprocket chain iscarried by the sprocket wheels 16, mounted on the shafts 17, suitablysupported in bearings 18, and said bearings may be mounted in theindividual floors of the building so as to operate the machinery on theseparate floors. The edges of the opening 14, are oppositely shoulderedas at 19, and pivoted in the recessed portion thus formed, by means ofthe pins 20, are the pawls 21, having the pointed and hooked ends 22, toengage the sprocket chain. These pawls are held in operative engagementwith the chain by means of the springs 23, and one of the pawls engagesthe chain on the downward stroke and the other on the upward stroke ofthe lever so that the chain is given a constant motion. A fly wheel 24,may be mounted on the shaft carrying the sprocket wheel to govern thespeed of the same. A spacing block 25, is mounted between the sprocketchain to prevent the same from sagging and moving out of engagement withthe pawls.

From this description taken in connection with the drawings, theoperation and advantages of my improved mechanism will be readilyappreciated, and it will be seen that it may be applied to a variety ofpurposes.

I claim:

1. In a power mechanism, the combination with a driven crank, and aslotted lever operated thereby, of a second lever having slidingconnection with the first lever, a sprocket chain and wheels, saidsecond lever being provided with pawls having connection with thesprocket chain.

2. The combination with a driven crank, of a lever having slidingconnection therewith, a second lever having sliding connection with thefirst lever, a sprocket chain and sprocket wheels, pawls carried by thesecond lever to engage said sprocket chain and means for spacing theopposite sides of the chain.

3. The combination with a driven crank, of a slotted lever in connectiontherewith, a

second lever having sliding connection with the first lever, a sprocketchain passing through an opening in the second lever, and pawls in thelever adjacent said opening adapted to engage opposite sides of thechain to operate the sprocket chain.

4. The combination with a driven crank disk, a slotted lever having itslong arm connected thereto, the short arm of said lever formed with aloop, a second lever having its. long arm formed with a correspondingloop in engagement with saidfirst loop, the opposaid pawls, and aspacing block between the site end of the second lever having a longi-0p osite sides of said chain. 10 tudinal opening near the end thereof,there 11 testimony whereof I affix my signature being recesses on theupper and lower faces at in presence of two witnesses.
